Utrecht's ancient city centre features many buildings and structures several dating as far back as the High Middle Ages. It has been the religious centre of the Netherlands since the 8th century. Currently it is the see of the Archbishop of Utrecht, the most important Dutch Roman Catholic leader. Utrecht is also the see of the archbishop of the Old Catholic church, titular head of the Union of Utrecht, and the location of the offices of the main Protestant church. Utrecht was the most important city in the Netherlands until the Dutch Golden Age, when it was succeeded by Amsterdam as the country's cultural centre and most populous city.

Utrecht is host to Utrecht University, the largest university in the Netherlands, as well as several other institutes for higher education. Due to its central position within the country, it is an important transport hub for both rail and road transport. It has the second highest number of cultural events in the Netherlands, after Amsterdam.

History

Origins (until 650)

Although there is some evidence of earlier inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE) and settling in the Bronze Age (app. 1800–800 BCE), the founding date of the city is usually related to the construction of a Roman fortification (castellum), probably built in around 50 CE.
A series of such fortresses was built after the Roman emperorClaudius decided the empire should not expand north. To consolidate the border the limes Germanicus defense line was constructed along the main branch of the river Rhine, which at that time flowed through a more northern bed compared to today (what is now the Kromme Rijn). These fortresses were designed to house a cohort of about 500 Roman soldiers. Near the fort settlements would grow housing artisans, traders and soldiers' wives and children.

In Roman times, the name of the Utrecht fortress was simply Traiectum, denoting its location at a possible Rhine crossing. Traiectum became Dutch Trecht; with the U from Old Dutch "uut" (downriver) added to distinguish U-trecht from Maas-tricht. In 11th-century official documents it was Latinized as Ultra Traiectum.
Around the year 200, the wooden walls of the fortification were replaced by sturdier tuff stone walls, remnants of which are still to be found below the buildings around Dom Square.

From the middle of the 3rd century Germanic tribes regularly invaded the Roman territories. Around 275 the Romans could no longer maintain the northern border and Utrecht was abandoned.[1] Little is known about the next period 270–650. Utrecht is first spoken of again several centuries after the Romans left. Under the influence of the growing realms of the Franks, during Dagobert I's reign in the 7th century, a church was built within the walls of the Roman fortress.[1] In ongoing border conflicts with the Frisians this first church was destroyed.

Centre of Christianity in the Netherlands (650–1579)

By the mid-7th century, English and Irish missionaries set out to convert the Frisians. The pope appointed their leader, Willibrordus, bishop of the Frisians. The tenure of Willibrordus is generally considered to be the beginning of the Bishopric of Utrecht.[1] In 723, the Frankish leader Charles Martel bestowed the fortress in Utrecht and the surrounding lands as the base of the bishops. From then on Utrecht became one of the most influential seats of power for the Roman Catholic Church in the Netherlands.
The archbishops of Utrecht were based at the uneasy northern border of the Carolingian Empire. In addition, the city of Utrecht had competition from the nearby trading centre Dorestad.[1] After the fall of Dorestad around 850, Utrecht became one of the most important cities in the Netherlands. The importance of Utrecht as a centre of Christianity is illustrated by the election of the Utrecht-born Adriaan Florenszoon Boeyens as pope in 1522 (the last non-Italian pope before John Paul II).

Prince-bishops

When the Frankish rulers established the system of feudalism, the Bishops of Utrecht came to exercise worldly power as prince-bishops.[1] The territory of the bishopric not only included the modern province of Utrecht (Nedersticht, 'lower Sticht'), but also extended to the northeast. The feudal conflict of the Middle Ages heavily affected Utrecht. The prince-bishopric was involved in almost continuous conflicts with the Counts of Holland and the Dukes of Guelders. The Veluwe region was seized by Guelders, but large areas in the modern province of Overijssel remained as the Oversticht.

Clerical buildings

Several churches and monasteries were built inside, or close to, the city of Utrecht. The most dominant of these was the Cathedral of Saint Martin, inside the old Roman fortress. The construction of the present Gothic building was begun in 1254 after an earlier romanesque construction had been badly damaged by fire. The choir and transept were finished from 1320 and were followed then by the ambitious Dom tower.[1] The last part to be constructed was the central nave, from 1420. By that time, however, the age of the great cathedrals had come to an end and declining finances prevented the ambitious project from being finished, the construction of the central nave being suspended before the planned flying buttresses could be finished.[1]
Besides the cathedral there were four collegiate churches in Utrecht: St. Salvator's Church (demolished in the 16th century), on the Dom square, dating back to the early 8th century. Saint John (Janskerk), originating in 1040; Saint Peter, building started in 1039 and Saint Mary's church building started around 1090 (demolished in the early 19th century, cloister survives).
Besides these churches the city housed Saint Paul's Abbey. The 15th-century beguinemonastery of Saint Nicholas, and a 14th-century chapter house of the Teutonic Knights.

Besides these buildings which belonged to the bishopric; an additional four parish churches were constructed in the city: the Jacobikerk (dedicated to Saint James), founded in the 11th century, with the current Gothic church dating back to the 14th century; the Buurkerk (Neighbourhood-church) of the 11th-century parish in the centre of the city; Nicolaichurch (dedicated to Saint Nicholas), from the 12th century and the 13th-century Geertekerk (dedicated to Saint Gertrude of Nivelles).

City of Utrecht

The location on the banks of the river Rhine allowed Utrecht to become an important trade centre in the Northern Netherlands. The growing town Utrecht was granted city rights by Henry V in 1122.
When the main flow of the Rhine moved south, the old bed, which still flowed through the heart of the town became evermore canalized; and the wharf system was built as an inner city harbour system. On the wharfs storage facilities (werfkelders) were built, on top of which the main street, including houses was constructed. The wharfs and the cellars are accessible from a platform at water level with stairs descending from the street level to form a unique structure. The relations between the bishop, who controlled many lands outside of the city, and the citizens of Utrecht was not always easy.[1] The bishop, for example dammed the Kromme Rijn at Wijk bij Duurstede to protect his estates from flooding. This threatened shipping for the city and led the city of Utrecht to commission a canal to ensure access to the town for shipping trade: the Vaartse Rijn, connecting Utrecht to the Hollandse IJssel at IJsselstein.

The end of independence

In 1528 the bishop lost secular power over both Neder- and Oversticht – which included the city of Utrecht – to Charles V, Holy Roman Emperor. Charles V combined the Seventeen Provinces (the current Benelux and the northern parts of France) as a personal union. This ended the prince-bishopric Utrecht, as the secular rule was now the lordship of Utrecht, with the religious power remaining with the bishop, although Charles V had gained the right to appoint new bishops. In 1559 the bishopric of Utrecht was raised to archbishopric to make it the religious center of the Northern ecclesiastical province in the Seventeen provinces.

The transition from independence to a relatively minor part of a larger union was not easily accepted. To quell uprisings Charles V was struggling to exert his power over the citizens of the city, who had struggled to gain a certain level of independence from the bishops and were not willing to cede this to their new lord. The heavily fortified castle Vredenburg was built to house a large garrison whose main task was to maintain order in the city. The castle would last less than 50 years before it was demolished in an uprising in the early stages of the Dutch Revolt.

Republic of the Netherlands (1579–1806)

In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.

The fortified city temporarily fell to the French invasion in 1672 (the Disaster Year); where the French invasion was only stopped west of Utrecht at the Old Hollandic Waterline. In 1674, only two years after the French left, the centre of Utrecht was struck by a tornado. The halt to building before construction of flying buttresses in the 15th century now proved to be the undoing of the central section of the cathedral of St Martin church which collapsed; creating the current Dom square between the tower and choir. In 1713, Utrecht hosted one of the first international peace negotiations when the Treaty of Utrecht settled the War of the Spanish Succession. Since 1723 Utrecht became the centre of the non-Roman Old Catholic Churches in the world.

Modern history (1815–present)

In the early 19th century, the role of Utrecht as a fortified town had become obsolete. The fortifications of the Nieuwe Hollandse Waterlinie were moved east of Utrecht. The town walls could now be demolished to allow for expansion. The moats remained intact and formed an important feature of the Zocher plantsoen, an English style landscape park that remains largely intact today. Growth of the city increased when, in 1843, a railway connecting Utrecht to Amsterdam was opened. After that, Utrecht gradually became the main hub of the Dutch railway network. With the industrial revolution finally gathering speed in the Netherlands and the ramparts taken down, Utrecht began to grow far beyond the medieval centre. In 1853, the Dutch government allowed the bishopric of Utrecht to be reinstated by Rome, and Utrecht became the centre of Dutch Catholicism once more. From the 1880s onward neighbourhoods such as Oudwijk, Wittevrouwen, Vogelenbuurt to the East, and Lombok to the West were developed. New middle class residential areas, such as Tuindorp and Oog in Al, were built in the 1920s and 1930s. During this period, several Jugendstil houses and office buildings were built, followed by Rietveld who built the Rietveld Schröder House (1924), and Dudok's construction of the city theater (1941).

During World War II, Utrecht was held by the Germans until the general German surrender of the Netherlands on 5 May 1945. Canadian troops that surrounded the city entered it after that surrender, on 7 May 1945. After the end of World War II, the city has grown considerably when new neighbourhoods such as , Kanaleneiland, and Lunetten were built. Around 2000 the city the Leidsche Rijn housing area was developed as the next extension of the city to the west.

The area surrounding Utrecht Centraal railway station and the station itself were developed following modernist ideas of the 1960s, in a brutalist style. This led to the construction of the shopping mall , music centre Vredenburg (Hertzberger, 1979), and conversion of part of the ancient canal structure into a highway (Catherijnebaan). Protest against further modernisation of the city centre followed even before the last buildings were finalised. In the early 21st century the whole area is being redeveloped. The music redeveloped music centre opened in 2014 where the original Vredenburg concert and rock and jazz halls are brought together in a single building.
